Figure 4 Separation of the cancer (filled squares) and control groups (empty squares) using principal component analysis (A), partial least squares- discriminant analysis (B), and orthogonal partial least squares discriminant analysis (C) in global profiling of urine samples in two-dimensional score plots[96]. These methods revealed that certain metabolites are involved in the separation of the two groups. OPLS: Orthogonal partial least squares; PC: Principal component.
